| Description: |
...The LFC789D25 is a dual linear FET controller that simplifies the design of dual power supplies. The deviceconsists of two independent controllers, each of which drives an external MOSFET to implement a low-dropoutregulator. One controller is programmed to regulate a fixed 2.5-V output, while the second controller can beprogrammed to regulate any desired output voltage via a reference input pin, allowing for the creation of a... ...easily can be isolated from the controllers, the controllers can regulate the output voltages to a maximumtolerance of ±2% across temperature and load.The LFC789D25 allows designers a great deal of flexibility in selecting external components and topology toimplement their specific power-supply needs. With appropriate heat sinking, the designer can build a regulator... ...Both drivers essentially are error amplifiers that can output a worst-case minimum of 9 V (10.5 V at 25°C) whenthe LFC789D25 is powered by 12 V. This allows the controllers to regulate a large range of outputvoltages, as limited by the threshold voltages of the external NMOS. Both drivers sample the output voltage viaa SEN pin. For the adjustable version, this SEN pin typically sources a current of 20 nA and, thus, has minimal... |
